Abstract: This paper studied on the adaptability of perch seedlings to chlorine in the sea water from the nano catalytic electrolysis disinfection treatment. The results showed that with the increase of the equivalent of the electrolytic treatment and the amount of the chlorine in the water， the hatching rate of the perch fertilized egg decreased. When the electrochemical equivalent was controlled within 4.9 w?h/t ， the hatch rate of the sea water and that of non - residual chlorine of gas explosion sea water were similar. In the situation that electrolytic equivalent was 9.6 w?h/t ，the residual chlorine content of treatment seawater was about 1.3 mg/L， which had a greater impact on the survival rate of the perch larvae. After mixed by the thiosulfat and removing the electrolysis residual chlorine in seawater， the growing seedlings effect was improved for the normal breeding of perch.
